Exclamation CEL NIGHTMARE HELP! p0491 code

Hello Fellow Bimmer lovers..

Purchased my first 03 745li LOVE the CAR Runs perfect drives like a dream, however NOT going to PASS State inspection...

I am getting Check Engine Light about every 3 days after reset code P0491 this is the only code.

Already changed all Vacum lines ALL NEW to check valve on passanger side new check valve new secondary air pump all brand new still getting this dreaded code any other ideas would be GREATLY apperciated???

I have doubled checked all housed several times replaced every part I know to replace I did see someone replaced CCV's which I have not does anyone think I should??

Thanks Chris
